Hi,
I have a char vector with year values. Some cells have single year
value '2001-' and some have range like 1996-2007.
I need to remove hyphen character '-' from all the values within the
character vector named as 'end'. After removing the hyphen I need to
get the last
number from the cells where there are year range values i.e if the
cell has range 1996-2007, the code should return me 2007.
How could I get this done?
Below are the values within this char vector:
> end
[1] "2001-" "1992-" "2013-" "2013-"
"2013-" "2013-"
[7] "2003-" "2010-" "2009-" "1986-"
"2012-" "2003-"
[13] "2005-" "2013-" "2003-" "2013-"
"1993–2007, 2010-" "2012-"
[19] "1984–1992, 1996-" "2015-" "2009-" "2000-"
"2005-" "1997-"
[25] "2012-" "1997-" "2002-" "2006-"
"1992-" "2007-"
[31] "1997-" "1982-" "2015-" "2015-"
"2010-" "1996–2007, 2011-"
[37] "2004-" "1999-" "2007-" "1996-"
"2013-" "2012-"
[43] "2012-" "2010-" "2011-" "1994-"
"2014-"
I tried below command--> gsub('[-|,]', '', end)
This did remove all the hyphen character but not from cells having
range year values.Below is the result after executing above command:
As you see hypphen character is removed from single values but not
from ranges. Please guide.
> gsub('[-|,]', '', end)
[1] "2001" "1992" "2013" "2013"
"2013" "2013" "2003"
[8] "2010" "2009" "1986" "2012"
"2003" "2005" "2013"
[15] "2003" "2013" "1993–2007 2010" "2012"
"1984–1992 1996" "2015" "2009"
[22] "2000" "2005" "1997" "2012"
"1997" "2002" "2006"
[29] "1992" "2007" "1997" "1982"
"2015" "2015" "2010"
[36] "1996–2007 2011" "2004" "1999" "2007"
"1996" "2013" "2012"
[43] "2012" "2010" "2011" "1994"
"2014"
